Show HN: I Spy AI – Detect AI-Generated Images, with an MCP Server

I Spy AI – Detect AI-Generated Images, with an MCP Server is active in the show hn launch space.

Profile

I built I Spy AI to detect AI-generated images — upload one on the dashboard or call it from any MCP client (Claude Desktop, Cursor, etc.) via the analyze_image tool.The detection runs on a separate FastAPI backend using pure OpenCV, no ML model, no GPU, just classical computer vision techniques looking for the artifacts diffusion models leave behind. The Next.js app handles auth, billing (Dodo Payments), and proxies images as raw binary to keep latency low. Async polling on the frontend.Inspiration came from r/isthisai where people there spend a lot of energy arguing whether images are real, and existing detectors are either gated behind enterprise sales or unreliable black-box classifiers.

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Its current recorded stage is Show HN launch.
